Reproduce the EIP6963.org scenario in the MetaMask in-app browser and trace the EIP-6963 provider identity and icon handling. The issue names no source file, test, or acceptance criteria, so first identify where the displayed name and icon come from; completion is not defined beyond changing the shown branding.
